Ideal for automotive tooling applications, such as High Pressure Die Cast (HPDC) inserts, tooling inserts, tire sipes & molds, & other high strength components.
Material & Process Capability
M300 Tool Steel is an ultra-low carbon alloy with very high strength & hardness properties derived from intermetallic compounds rather than carbon content. The material is comprised mainly of nickel, with cobalt, molybdenum, & titanium as secondary intermetallic alloying metals.
It is ideal for tooling applications such as High Pressure Die Cast (HPDC) inserts, injection molding, and other types of tooling.
The Velo3D fully integrated manufacturing solution uniquely enables companies to build the parts they need without compromising design or quality – resulting in complex parts higher in performance than traditional casting techniques or other additive methods.
This data sheet specifies the expected mechanical properties and characteristics of this alloy when manufactured on a Velo3D Sapphire System. All data is based on parts built using Velo3D standard 50 μm layer thickness parameters, using Praxair FE-339-3, a Velo3D-approved powder. Parts built from M300 on a Sapphire System can be heat treated like those manufactured by other methods.
